Assessing the severity of valve stenosis.

Aortic valve resistance as an adjunct to the Gorlin formula in assessing the severity of aortic stenosis in symptomatic patients.

OBJECTIVES This study was conducted to determine the utility of aortic valve resistance in assessing the severity of aortic stenosis. BACKGROUND Assessment of the severity of aortic stenosis has traditionally employed hemodynamic data and the Gorlin formula to calculate the area of the aortic valve. Recently, flow dependence of the Gorlin formula has been identified and the accuracy of the fo...

Mitral Leaflet Separation Index in Assessing the Severity of Mitral Stenosis

Determining the severity of mitral stenosis (MS) is important for both prognostic and therapeutic reasons. The mitral valve area (MVA) can be measured by planimetry, pressure half-time, continuity equation, and proximal isovelocity surface area methods. In this study, we propose a novel yet simple, independent measure of MS severity-the mitral leaflet separation (MLS) index. This new index coul...

Stenosis is in the eye of the observer: impact of pressure recovery on assessing aortic valve area.

Severity of aortic stenosis. The study by Garcia et al. (1) in this issue of the Journal has bearing on a long-standing clinical quandary: Doppler continuity aortic valve areas (2,3), taken in the context of typical catheterization valve area cutoff values (4,5), often appear to produce misclassification toward higher degrees of severity, particularly in patients with relatively mild obstructio...

Accuracy of the Phonocardiogram in Assessing Severity of Aortic and Pulmonic Stenosis.

بررسی بالینی و اکوکاردیوگرافیک تنگی دریچه میترال در بیماران مراجعه کننده به بیمارستان های امام خمینی و امیراعلم1

Rheumatic heart disease is a serious health problem in developing countries. The present study was conducted to evaluate clinical and echocardiographic findings of Mitral stenosis and their relationship with patients functional classes. We studied records of 400 patients with symptomatic mitral stenosis (71% female, mostly in 20s or 30s and 54% function class II) treated in two hospitals in Teh...
